RESUMO
OBJECTIVES: To assess the visualization rate and size of the frontal horns (FHs) and cavum septi pellucidi (CSP) in healthy fetuses throughout pregnancy. METHODS: After Institutional Review Board approval, 522 consecutive uncomplicated singleton pregnancies between 15 and 39 gestational weeks were enrolled in the study. Ultrasound measurements of the anterior horn width (AHW), center from the horn distance (CFHD), distance from the FHs to the CSP, and CSP width were retrospectively performed using axial transventricular or transcerebellar planes. Available maternal body mass indices were recorded. RESULTS: At least 1 FH was seen in 78% of the cases. The mean AHW decreased over the second trimester and plateaued in the third trimester. The CFHD plateaued in the second trimester and increased in the third trimester. Downside FHs were generally larger than upside FHs. More FHs were measured in transventricular (69%) than transcerebellar (31%) planes. Frontal horns were seen with high, low, and no confidence in 57%, 21%, and 22% of cases, respectively. No-confidence rates were 17% in the second trimester and 42% in the third trimester. The CSP was not visualized in 4% of cases; 15 of 19 cases of a nonvisualized CSP were scanned between 18 and 37 weeks. Mean body mass indices ± SDs were 27.6 ± 6.7 kg/m2 for the patients in cases of a visualized CSP and 32.4 ± 9.1 kg/m2 for the patients in cases of a nonvisualized CSP. CONCLUSIONS: Normative data for the fetal FH and CSP width were established. Frontal horns are more frequently seen on transventricular views and are difficult to confidently assess in the late third trimester. This study challenges previously reported data that the CSP is seen in 100% of cases from 18 to 37 weeks.

AIM: The aim of this study was to evaluate if thong use is associated with a higher report of urogenital infections, including urinary tract infections, yeast vaginitis and bacterial vaginosis. METHODS: A cross-sectional survey regarding underwear preferences and infectious history was designed and distributed to women via a crowdsourcing service. All survey questions related to the last 12 months. Parametric and nonparametric statistical methods were used to compare responses between thong wearers and nonthong wearers. Thong wearers were defined as women who wore a thong equal to or more than 50 % of the time. RESULTS: Nine hundred and eighty-six respondents met inclusion criteria and completed the survey; 186 (18.9%) were defined as thong wearers and 800 (81.1%) were defined as nonthong wearers in the last 12 months. Reported rates of urogenital infections in the last 12 months were not significantly different for thong wearers versus nonthong wearers. Thong use was not an independent predictor of any urogenital infection in this study. CONCLUSION: In this large cross-sectional study we found that oral sex was the only independent predictor of urinary tract infection and bacterial vaginosis, and that wearing noncotton crotch underwear was associated with yeast vaginitis. Wearing thong underwear was not associated with any urogenital infections. Medical providers should discuss sexual practices and underwear fabric, rather than style, with their patients when there is concern for urogenital infection.

Fragile X-associated tremor ataxia syndrome (FXTAS) is a late onset neurodegenerative disease that affects carriers of the fragile X premutation. This study seeks to assess hypertension risk and susceptibility in male premutation carriers with FXTAS. Although many symptoms and diagnostic criteria have been identified, hypertension risk has not been examined in this population. Data from 92 premutation carriers without FXTAS, 100 premutation carriers with FXTAS, and 186 controls was collected via patient medical interview. Age-adjusted logistic regression analysis was used to examine the relative odds of hypertension. We observed a significantly elevated odds ratio (OR) of hypertension relative to controls for premutation carriers with FXTAS (OR = 3.22, 95% CI: 1.72-6.04; P = 0.0003) among participants over 40-year old. The age-adjusted estimated odds of hypertension in premutation carriers without FXTAS in the over 40-year-old age group was higher compared to controls (OR = 1.61, 95% CI: 0.82-3.16), but was not statistically significant (P = 0.164). Chronic hypertension contributes to cardiovascular complications, dementia, and increased risk of stroke. Our results indicate that the risk of hypertension is significantly elevated in male premutation carriers with FXTAS compared with carriers without FXTAS and controls. Thus, evaluation of hypertension in patients diagnosed with FXTAS should be a routine part of the treatment monitoring and intervention for this disease.

The relative risk of immune-mediated disorders (IMDs) among women carriers of premutation alleles is estimated by a survey for IMDs among 344 carrier women (age 19-81 years; mean 46.35 and SD 12.60) and 72 controls (age 18-87 years; mean 52.40 and SD 15.40). One hundred fifty four (44.77%) women carrier had at least one IMD, as did 20 controls (27.78%). Among women carriers, autoimmune thyroid disorder was the most common (24.4%), then fibromyalgia (10.2%), irritable bowel syndrome (IBS; 9.9%), Raynaud's phenomenon (7.6%), rheumatoid arthritis (RA; 3.8%), Sjögren syndrome (2.6%), systemic lupus erythematosus (SLE; 2.03%), multiple sclerosis (1.74%). Of 55 carriers age 40 or older with FXTAS, 72.73% had at least one IMD, compared to 46.54% of those without FXTAS (n = 159), and 31.58% of controls (n = 57). The estimated odds ratio (OR) for IMD is 2.6 (95% CI 1.2-5.6, P = 0.015) for women with FXTAS relative to those without FXTAS; the likelihood of IMD in carriers without or with FXTAS was also significantly higher than for controls (OR 2.1, 95% CI 1.1-4.2, P = 0.034; OR 5.5, 95% CI 2.4-12.5, P < 0.001, respectively). Similarly, the odds of having an IMD among carriers with FXPOI is about 2.4 times higher when compared to carriers without FXPOI (95% CI 1.1-5.0; P = 0.021). The likelihood of IMD in carriers with or without FXPOI is greater (OR 2.4, 95% CI 1.1-5.0; P = 0.021) compared to that of controls.

This report seeks to establish the prevalence of sleep apnea in patients with the fragile X mental retardation 1 (FMR1) premutation with and without fragile X-associated tremor/ataxia syndrome (FXTAS) and to determine any correlation between CGG repeat and FMR1 mRNA levels with sleep apnea prevalence. Demographic and medical data from 430 (229 males, 201 females) participants were used in this analysis. Participants included premutation carriers with (n = 118) and without FXTAS (n = 174) as well as controls without the premutation (n = 123). Logistic regression models were employed to estimate the odds ratio of sleep apnea relative to controls, adjusted for age and gender, and also to examine potential association with CGG size and FMR1 mRNA expression level. The observed proportion of sleep apnea in premutation carriers with and without FXTAS and controls are 31.4% (37/118), 8.6% (15/174), and 13.8% (17/123), respectively. The adjusted odds of sleep apnea for premutation carriers with FXTAS is about 3.4 times that compared to controls (odds ratio, OR = 3.4, 95% confidence interval (CI) 1.8-7.4; P = 0.001), and similarly relative to premutation carriers without FXTAS (OR = 2.9, 95% CI 1.2-6.9; P = 0.014). The risk of sleep apnea was not different between controls and premutation carriers without FXTAS. The presence of sleep apnea is not associated with CGG repeat numbers nor FMR1 mRNA expression level among premutation carriers. Our data supports a higher prevalence and risk of sleep apnea in patients with FXTAS. We recommend that all patients diagnosed with FXTAS be screened for sleep apnea given the negative and perhaps accelerative impact sleep apnea may have on their FXTAS progression.

Objective: We hypothesized that women with a positive antenatal Edinburgh Depression Screen (EPDS) (≥10), undergoing behavioral or pharmacologic therapy have improved maternal and neonatal outcomes.Study design: This is a retrospective study of singleton pregnancies at UC, San Diego from 2010 to 2014. Patients with an antenatal EPDS were subdivided based on their intervention: negative score, positive score no treatment, behavioral therapy only, and pharmacologic therapy. The primary outcome was rate of preterm birth with secondary outcomes of maternal and neonatal outcomes.Results: Patients with a positive EPDS had a higher rate of preterm delivery, small-for-gestational age, NICU admission and Apgar score <7. Rates of adverse outcomes were highest among women receiving pharmacologic therapy. Rates of adverse outcomes women were not increased in the behavioral therapy group compared to the negative EPDS group. When adjusting for confounding variables, patient with a positive EPDS were more likely deliver preterm with an adjusted odds ratio of 1.71. Among varying treatment modalities, the odds ratio for preterm delivery was not statistically significant.Conclusion: Adverse pregnancy outcomes were highest among those requiring pharmacotherapy. Behavioral therapy had a positive effect on outcomes. Intervention to reduce these adverse outcomes in these patients needs further study.

Patients undergoing assisted reproduction are advised to abstain from intercourse to prevent the possibility of multiple pregnancy. If patients do not follow this advice, multiple dizygotic pregnancy or even a heterotopic pregnancy can result. We report the case of a 28-year-old nulliparous female with unexplained infertility who underwent freeze-all vaginal oocyte retrieval. Twenty-one days later she presented with vaginal bleeding (similar to menstruation) and right lower-quadrant pain. The results of ultrasound scanning and a laboratory work-up were consistent with an ectopic pregnancy. She underwent laparoscopic right salpingectomy for a tubal ectopic pregnancy. We recommend sexual abstinence during assisted reproduction to lower the risk of multiple pregnancy and especially of heterotopic pregnancy.
RESUMO
OBJECTIVE: To evaluate 24 hour urine exosome protein content changes among pregnant US subjects with diabetes and obesity during early pregnancy. METHODS: The exosome proteome content from 24 hour urine samples of pregnant subjects with gestational diabetes mellitus (GDM, N=8) and pre-gestational Type 2 diabetes (PGD, N = 10) were compared with control samples (CTRL, N = 10) obtained at week 20 of pregnancy. Differences in exosome protein load between groups was identified by liquid chromatography/mass spectrometry, analyzed by linear regression in negative binomial distribution, visualized in MetaboAnalyst (version 3.0), and validated by western immunoblotting. RESULTS: At the 20th week of pregnancy, we identified 646, 734 and 856 proteins in exosomes from 24 hour urine samples of patients from the CTRL, GDM and PGD groups, respectively. S100 calcium binding protein A9, damage associated molecular pattern (DAMP) signal, was found to be significantly increased in both GDM and PGD subjects. In GDM subjects the peptide counts for S100A9 protein independently correlated with maternal obesity and macrosomia of the newborn infants. Early to late pregnancy developmental changes in the GDM group were shown to utilize pathways and protein expression levels differently from those in PGD or CTRL groups. CONCLUSIONS: Urinary exosome proteomic analysis non-invasively provides insights into maternal changes during diabetic pregnancy. Exosome biomarkers early in pregnancy can be potentially used to better understand pathophysiologic mechanisms of diabetes at a cellular level, and to distinguish between gestational and pre-gestational diabetes at the pathway level. This information can aid intervention efforts to improve pregnancy outcomes in women with diabetes.
